I No. 887,678.

Specification of Letters Patent.

Patented May 12, .1908.

Application filed July 20, 1907. Serial No. 384,718.

To all who m it may concern:

Be it known that I, GUSTAF E. VVALLIN, a

-' citizen of the United States, residing at Kanf a specification.

This invention relates to a device designed for permitting the operator of a linotype ma chine to obtain wide spacing of the type or words in evening the lines or where large type 'is used, necessitating a space wider than t 1e ordinary wedges of the machine will produce, and it relates more particularly to an attachment adapted to be applied to the space bar at the head of the keyboard of a linotype machine for enabling the above results to be readily accomplished.

The invention has for one of its objects to provide a device of the character referred to which is comparatively easy and inexpensive to manufacture, readily applied to machines without requiring any changes or alterations, and which possesses the advantage of eliminating a large amount of hand spacing.

A further object of the invention is the provision of an attachment for the space bar of the keyboard whereby either the N quad key or thin space key can be simultaneously depressed with the space bar for the purpose of causing an N quad or thin space quad to be deposited simultaneously with the droping' of a wedge spacer into the assembler.

With these objects in view and others, as

will appear as the description proceeds, the

invention comprises the various novel features of construction and arrangement of arts which will be more fully described ereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawing, which illustrates one of the embodiments of the inven tion, Figure 1 represents a plan view of a portion of the space bar showing the invention applied thereto in cooperative relation with the N quad and thin space keys. Fig. 2 is a perspective view of a key-board of a linotype machine showing my improved attach ment applied thereto.

Referring to the drawing, 1 designates the space bar of usual construction and located at the head or top of the keyboard of the linotype machine and mounted on swinging arms, one of which is indicated at 2. The usual prcsser arm at the left hand end of the bar 1 is dispensed with and a swinging arm 3 used in its stead, the said arm being pivoted at a and provided with a short arm 5 that has teeth or notches 6 in its end edge. Cooperating with the notched member of the arm 3 is a pawl 7 ivoted on the space bar at 8 and held yie dingly into engagc ment with the teeth 6 by a spring 9 fixed on the space bar to engage behind the pawl. At a point directly above the N qua and thin space keys is secured to the space bar 1, a plate 10 that supports a pivoted T- shaped member 11 that is adapted to be actuated by the arm 3 through a connecting rod 12. The oppositely extending arms 13 and 14 of the member 11 are adapted to engage respectively over the this space key and N quad key so as to engage the bars thereof when the arm 3 is turned to the right or left, portions of the bars beingindicated at 15. The arm 3 is adapted to have three different positions, as shown, and the spring-pressed pawl locks the arm in any one position, and in order to shift the arm, it is merely necessary to apply ressure thereto in the proper direction and t 1e pawl will yield to permit the teeth to pass thereunder and then automatically lock the arm in fixed position. When the arm is in central position, the T-shaped member 11 lies between the key bars 15 .so that the space bar 1 can be depressed without depressing either of the keys 16 or 1?. WV hen the arm 3 is thrown to the right or left, as shown by dotted lines, the member 11 will be shifted to lie over one or the other of the key bars so that the space bar can be depressed, together with either of the keys 16 or 17, since the member 11 moves with the space bar. It will thus be seen that by throwing the arms 3 to one side or the other, an IN quad or thin space iece can be de osited in the assembler of t 1e linotype mac he at the same time with the dropping of the wedge space, as the operator depresses the space bar in the usual manner.

From the foregoing description, taken in connection with the accompanying drawing, the advantages of the construction and of the method of operation will be readily Cir apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the apparatus which I now consider tobe the best embodiient thereof, I desire to have it understood 7 that such changes may be made. when desired,- as are within-the scope of the claims.

Having thus described the invention, what I claim is 1. An attachment for linotype machines comprising an. adjustable member attached to the space bar of the keyboard, and a device on the keyboard controlled by the member for engaglng one or more quad controlling keys to operate the same simultaneously with the actuation of the space bar.

2. An attachment for linotype machines carried entirely by the space bar of the keyboard, said attachment comprising a device adapted to be brought into cooperative relation with one or more quad controlling keys, a member mounted on the bar at one side of the keyboard for depressing the bar, a connection between the member and device for setting the latter, and a locking means for bar adapted to .be thrown into cooperative relation with one or more of the quad controlling keys, and a connecting rod between the member and device.

4. In a linotype machine, the combination of a space bar for the keyboard, an adjustable member thereon for depressing the space bar, and means carried by and movable with the space bar and controlled by the gagement with one or more of the quad. controlling keys, and a connecting means between the arm and member.

6. The combination of a keyboard and a its space bar of a linotype machine, with means associated with the bar for actuating a quadcontrolling key simultaneously with the operation of the space bar.

In testimony whereof, I afiix my signature in presence of two witnesses.

GUSTAF E; WALL'IN.
